This isn't exactly an astronomy project but i hope I'm ok to post.
I am building a wireless dmx system using
these components:
DMX Controller
2.4G nRF24L01 Wireless Module w / PA and LNA
Arduino Pro Mini
50W DC 30-36V 1500mA high Power LED Constant Current driver AC 85-265V IN
This is not the exact one, but a 50W constant current supply
50W RGB LED Flood Light
The issue I'm having is that when the LED turns off, the voltage that supplies the Aduino/RF circuit drops from 5/3.3v to about 1.9v. I assume this has something to do with the constant current supply. Is there some way I can induce a current accross the supply when the LED turn off?
Here is the circuit for the Arduino/RF board:

Thanks in advance for any advice!
EDIT: I should add, the entire thing including the DMX controller and Arduino/RF board are being supplied by the 40V 50W constant current PSU. The DMX Controller works fine whether the LEDs are on or off.
